Comparison GT Racer B-528 vs GT Racer B-517L

The highest weight that the chair is guaranteed to withstand with regular use — in other words, the maximum weight of a seated person, allowing you to constantly use the product in normal mode without fear of unexpected breakdown. Note that many models are able to endure short-term excess weight without problems, however, anyway, it is not worth overloading the structure (and even more so doing it all the time): off-design loads will significantly increase its wear, and breakdown can occur at the most unexpected moment.

Dimensions of the seat installed in the chair in width and depth (from the back to the front edge). For models with variable depth (see "Adjustments"), the maximum value is taken into account when the seat is pushed forward to the stop.

Most modern chairs are designed for the average adult, so paying attention to size is primarily for people of a large, or, conversely, miniature physique. In width, the average is considered to be 45 – 55 cm, the narrowest models are up to 40 cm wide, in the widest it can exceed 60 cm. Similarly, a depth of less than 40 cm is considered small, up to 60 cm — medium, more than 60 cm — large.

Seat height from the floor. The optimal height for an average person is considered to be 40 – 50 cm, however, this is largely subjective, and the comfort of the chair for a specific user greatly depends on their preferences and physical characteristics. In light of this, many models offer the ability to adjust the height within a certain range (see "Adjustments"). For the best choice, it's best to "try out" in person to determine at what height you feel comfortable sitting and find a model with the corresponding features.

The presence of an additional footrest in the design of the chair. Such a stand is usually made folding and located under the seat, and when unfolded it rises forward to a horizontal or almost horizontal position; On some models, the tilt of the stand can be adjusted. Anyway, this feature allows you to unload the legs, which not only provides additional comfort, but also has a positive effect on the ligaments and joints.

A built-in hanger is usually found in advanced models of computer chairs. Place it on the outside of the back. You can hang outerwear (for example, a jacket or vest) on a hanger without worrying that it will wrinkle.

The ability to change the height of the headrest. For more on the role of the function itself, see "Headrest"; here we note that this adjustment makes it easier to adjust the chair to the height of the user, however, it is possible to adjust the height of the headrest only if the headrest is a separate part, and not an extension of the backrest.

Changing the inclination of the headrest changes, accordingly, the inclination of the head resting on it. This allows the user to choose the optimal position for their preferences and specifics of the situation.

The ability to change the backrest tilt back and forth. Allows users to adjust the chair depending on how they prefer to sit: straight or slightly leaning back.

The ability to change the force required to tilt the chair (or only the backrest, if the seat is fixed). Swing stiffness adjustment provides adjustment to the weight and preferences of the individual user.
